  2. 11. Development of Novel In Situ ESEM Techniques for the Study of Water Interaction with Soft Materials

    Author : Anna Jansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; environmental scanning electron microscopy; cellulose fibre; water transport; swelling; osmotic shock; yeast cell; in situ; manipulator; water interaction;

    Abstract : The transport of water is central to many applications of soft biomaterials; for example water management in personal care products, controlled drug release in pharmaceuticals and, on a fundamental level, the activities of living cells. Water transport through a material may occur in both liquid and gas phase, and is highly dependent on the microstructure. READ MORE

  4. 12. Understanding overlooked molecular interactions in the cellulose/NaOH(aq) system

    Author : Maria Gunnarsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; ATR-IR; dissolution; cellulose; NMR; urea; CO2; NaOH aq ;

    Abstract : The cold NaOH(aq) system is a promising process for the production of textile fibres. Although the process has been studied for almost a century, there remain unsolved research issues, especially regarding the dissolution mechanism. READ MORE

  5. 13. On the Mechanism of Assembly of Xylans onto Cellulose Surfaces

    Author : Åsa Linder; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aggregation; Xylan; cellulose; surface structures; assembly;

    Abstract : Cellulose is the most abundant biopolymer on earth and the major component in cell walls of wood and terrestrial plants. Commercial applications include paper, plastics, hygiene and pharmaceutical products. The composition and morphology of cellulose surfaces affect the product properties. READ MORE

  6. 14. Bio-based preparation of nanocellulose and functionalization using polyelectrolytes

    Author : Jonatan Henschen; Monica Ek; Josefin Illergård; Dongfang Li; Emily Cranston; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cellulose nanofibrils; cellulose nanocrystals; oxalic acid; polyvinylamine; layer by layer; cellulose oxalate; antibacterial; Cellulosa nanofibriller; cellulosa nanokristaller; oxalsyra; polyvinylamin; lager på lager; cellulosa oxalat; antibakteriell; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Nanocellulosa, som kan utvinnas från skogsråvara, har de senaste åren fått mycket uppmärksamhet för sina intressanta egenskaper och breda användningsområde. Studierna i denna avhandling syftar till att vidga möjligheterna att använda nanocellulosa i olika applikationer. READ MORE

  7. 15. Bio-inspired polysaccharide nanocomposites and foams

    Author : Anna Svagan; Lars Berglund; Mats Stading; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cellulose; starch; microfibrillated cellulose; biomimetic; nanocomposite; nanocomposite foam; mechanical properties; Biomaterials; Biomaterial;

    Abstract : Today, the majority of materials used for single-use packaging are petroleum-based synthetic polymers. With increased concern about the environmental protection, efforts have been made to develop alternative biodegradable materials from renewable resources. Starch offers an attractive alternative since it is of low cost and abundant. READ MORE
